odor and windshiels fogging when heater on

I'm not sure what it will cost, but DON'T DRIVE YOUR CAR!! Those are the classic signs of the heater core failing and when it finally lets go, you'll have a pool of antifreeze in your passenger compartment and you'll have to shut off immediately. And this ususally happens at the most inopportune time.

As far as cost goes, members can speculate or relate what they paid but your best bet is to call your local indy shop and ask them. What you find locally is all that matters anyway. You could call the dealer to get a baseline.
